Cold Air Return Vents In Winter

My question/issue is that two of the returns and 3 of the supplies have pretty bad (cold) drafts throughout the winter.

Cold air return vents in winter. Cold air return vents at ceiling level. No never close off your cold air return.this causes the blower fan to starve for air reducing the units efficiency. In the summer time hot air rises and and is sucked through the ceiling vent, while in the winter time cold air falls and is sucked in through the floor vent.

Supply air from furnaces and air conditioners should be on outside walls. In the winter you want the cold air to be drawn through the return registers leaving the hot air behind. In an air conditioning climate the return duct goes near the ceiling to draw off the hot air and cool it down.

Ok, i've read a ton on this, and i can't get a straight answer. Heat rises, and cold air stays close to the floor. In a heating climate, the return duct goes near the floor to draw off the cold air and heat it up.

When the air turns on the fan sucks air into the return air vent, thus pulling the warm air from the ceiling and cooling it down, which keeps the house cool. A popular misconception about vents is that by shutting some you can improve the efficiency of others. Now in the winter time this system is not very.

If shut it starves the system of air, and if it can't suck it can't blow. There are 3 returns on the 2nd floor, and about 10 supply vents throughout both floors. This pulls the air across your body.

First of all, the furnace in their home was designed to blow hot air into every room in the house. If you have an air return is on the upper wall i like to slant the louvers upwards so that floor traffic does not view into the duct opening.
